Subject: Input: iforce - use ENOSPC instead of ENOMEM

Use -ENOSPC instead of -ENOMEM when the iforce device doesn't have
enough free memory for the new effect.  All other drivers are using
-ENOSPC, so this makes the behaviour coherent.

Subject: Input: fix accuracy of fixp-arith.h

Add the value of cos(90) = 0 to the table.  This also moves the results so
that sin(x) == sin(180-x) is true as expected.

Subject: Input: reset name, phys and uniq when unregistering

Name, phys and uniq are quite often constant strings in moules implementing
particular input device. If a module unregisters input device and then gets
unloaded, the device could still be present in memory (pinned via sysfs),
but aforementioned members would point to some random memory. Set them all
to NULL when unregistering so sysfs handlers won't try dereferencing them.

reported as EV_MSC/MSC_SCAN events.
